FIELD OF THE INVENTION

The present invention relates generally to the field of sleeping bags. More specifically, the present invention relates to an improved sleeping bag featuring integrated memory foam to provide comfort on hard surfaces and an adjustable heating element to keep individuals warm during cold outdoor temperatures. The sleeping bag comprises three heating zones to accommodate the head and neck area, back area and feet of the users. Each zone can be operated independently via a control panel. The heating zones of the sleeping bag include heating elements spread over different sections, that are powered using a standard power cord or a battery pack attached to a solar panel.

Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.

BACKGROUND OF THE INVENTION

By way of background, camping and hiking are enjoyed by individuals around the world. While camping or hiking, sleeping outdoors is an activity that is commonly performed by the users. Individuals usually carry sleeping bags along with other equipment while camping, hiking, hill walking, climbing or other similar adventures. Typical sleeping bags are lightweight, portable bedding comprising a covering or a quilt-like material in a tube-shaped structure, that can be closed with a fastening mechanism. Generally, the material of sleeping bags is relatively thin, and therefore most sleeping bags are unable to accommodate cold outdoor temperatures. When using sleeping bags in cold weather, individuals may not be insulated from the cooler ambient temperature and will be unable to enjoy the camping trip. Additionally, individuals may be uncomfortable and may not sleep properly inside the sleeping bag in cold weather conditions. Sleep discomfort negatively impacts the camping experience and can impact the subsequent activities of the trip.

Additionally, while camping, hiking or during other adventures, the surface on which sleeping bags are placed may be uneven, hard and stony. Standard sleeping bags are quite uncomfortable when used on hard and uneven ground. Individuals may be unable to sleep properly on the ground all night without proper padding in, or under, standard sleeping bags.

To overcome the above issues, individuals may carry mattresses or padding separately to support the sleeping bag over uneven surfaces. However, it becomes difficult to carry heavy mattresses or padding supports while camping, trekking and more, and puts additional burden on the individuals. Further, the mattresses may only provide a padded surface for sleeping bags, and individuals may still be unable to sleep properly in cold weather conditions.

Therefore, there exists a long felt need in the art for a sleeping bag that is lightweight and that can be easily be carried while camping, trekking, hiking and more. There is also a long felt need in the art for an improved sleeping bag that provides a comfortable experience while lying on sleeping bags placed on uneven and rocky ground. Additionally, there is a long felt need in the art for a sleeping bag that integrates padding support and allows the users to sleep comfortably all through the night while on the ground. Moreover, there is a long felt need in the art for a sleeping bag that prevents the users from cold weather conditions and allows them to sleep comfortably. Further, there is a long felt need in the art for a sleeping device that eliminates the need to carry additional mattresses or padding supports independently. Furthermore, there is a long felt need in the art for an improved sleeping bag that keeps individuals warm in the outdoors and prevents them from becoming cold and uncomfortable. Finally, there is a long felt need in the art for an improved sleeping bag that improves the overall outdoor sleeping experience.

The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a heated sleeping bag. More specifically, the sleeping bag includes: a generally rectangular memory foam base; the base having two longitudinal edges, a head end and a foot end; and, a waterproof top cover dimensioned to cover the memory foam base that attaches to the base along the longitudinal edges, the head end and the foot end. The foam base includes a plurality of integrated heating elements, wherein a first heating element is for a head and neck portion of the user, a second heating element is for a back and abdomen portion, and a third heating element is for legs and feet of the user. The heating of each heating element can be individually adjusted using a wired or wirelessly connected control panel. The heating elements receive power through an internal battery or directly through a plug and cord inserted into an electrical outlet.

In this manner, the novel heated sleeping bag of the present invention accomplishes all of the forgoing objectives, and provides a relatively easy and comfortable solution to allow the users to sleep comfortably inside the sleeping bag on hard and stony ground while camping, hiking, trekking, and more. The heated sleeping bag of the present invention is also user friendly, as it ensures the user stays warm in cold weather conditions and remains comfortable while sleeping outdoors. The integrated memory foam padding eliminates the need to carry mattresses or pads separately and improves the overall outdoor sleeping experience while camping, hiking, trekking and more.
